Keywords:
malezas ciperáceas, arroz, oryza sativa (es)cyperaceae weeds, rice, oryza sativa (en)
con la producción de arroz en Colombia. Se ha podido
observar diferencias en la respuesta a los herbicidas entre las
especies de ciperáceas, de ahí la necesidad de reconocer las
diferentes especies de esta familia que infestan los arrozales
de Colombia. Se realizó una intensiva colecta botánica de estas
especies en las principales zonas arroceras de Colombia:
Tolima, Huila, Meta, Córdoba, Cesar, Santander y Valle del
Cauca. Un total de 25 especies pertenecientes a nueve géneros,
fueron reconocidas. Se elaboraron claves para la separación
de géneros y especies.
